BUTTON.

SPECIFICATION forming part of Letters Patent No. 386,763, dated July 24,1888.

Application filed February 2, 1888. Serial No. 262,782.

To all whom it 71mg concern.-

Be it known that I, WILLIAM F. WHITING, of Providence,in the countyofProvidence and State of Rhode Island, have invented an Improvement inButtons, of which the following description, in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

This invention is an improvement upon the button or stud shown anddescribed in application for Letters Patent, Serial No. 261,723, filedJanuary 24, 1888, and has for its object to cheapcn the construction asmuch as possible. In accordance with this invention the pivotedshoe,working upon the rocker of the post, is made of two pieces only, anexternal cap and a spring-plate, the latter serving as the under plate.The springplate is made substantially as in the said application, itpresenting two spring arms and a central yielding tongue, and the edgeof the cap isv turned over upon the edge of the springplate to securethe parts together. The cap is provided at its interior and near oneedge with an abrupt projection, which serves as a stop, against whichthe outer edge of the rocker strikes when the shoe occupies a positionparallel with the head of the button or stud, while the end of theyielding tongue of the springplate serves as a stop for the rocker whenthe shoe occupies a position in line with the post.

Figure 1 shows in vertical section a button or stud, the shoe beingturned in line with the post; Fig. 2, a similar view, the shoe being inits normal position or parallel with the head; Fig. 3, a plan view ofthe springplate; Fig. 4, a plan view of the cap; and Fig. 5, a sideelevation ofthe button,the shoe being removed to show the rocker.

The head a, post 12, bent at b and having at its outer end the rocker b,are substantially as in the application referred to. The shoe iscomposed of two parts, the spring-plate i and the cap 2''.

similar to the corresponding plate in the application referred to, itbeing cut away, as at i, to present aspace in which the post 1) works,and also slitted, as at 2, to present two yielding arms, m m, and ayielding tongue, m, between them. The cap 2' is concavo convex,

The spring-plate i is made very (No model.)

and of sufficient size to receive the springplate, that its edges may beturned over upon the plate to hold the parts together. The cap hasformed upon its interior near one edge a projection, 3, preferably madeby indenting the cap. This projection 3 forms an abrupt stop orshoulder, against which the outer edge of the rocker b bears when theshoe is in the position shown in Fig. 2 or parallel with the head, inwhich position the arms of the rocker I; rest free beneath thespring-arms m m of the plate 2", and the convex side or face 4 of therocker bears on the yielding tongue m".

When the shoe is in the position shown in Fig. 1 or in line with thepost, the outer edge of the rocker b rests against the end of the tongueof. It will thus be seen that the tongue m" and stop 3 form the twostops for the rocker, which prevent the shoe slipping in one or theother direction, and the complete shoe being made in two pieces greatlycheapens the manufacture of the button or stud.

I claim-- 1. In a button or stud, the head, bent post, and rocker,combined with the shoe composed of the plate, slitted as at 2, andcutaway as at i, to present the spring-arms m m, and the stop in and thecap 1', substantially as described.

2. In a button or stud, the head, bent post, and rocker, combined withthe shoe composed only ofthe spring-armed under plate, cutaway as at i,and the cap, substantially as described.

3. In a button or stud, the head, bent post, and rocker, combined withthe shoe composed of the spring-armed under plate, 2", having the tonguem and cut away at t, and the cap 6 substantially as described.

4. In a button or stud, the head, post, and rocker, combined with theshoe composed only of the plate i, having the yielding tongue m", andthe cap 1",having the projection 3, substantially as described.

In testimony whereofI have signed my name to this specification in thepresence of two subscribing witnesses.
